In radio receivers, IQ errors (or IQ imbalance) can cause the radio to exhibit a poor signal-to-noise ratio or exhibit errors. As modulation schemes become more complex utilizing larger numbers of constellation symbols, the radios become less tolerant of IQ errors. Hence, conventional techniques that set the radio's operational parameters at the time of manufacture or at the time of power up are inadequate to achieve adequate signal-to-noise ratio (SNR) in more complex modulation schemes.
